THE ORANG-OUTAX.
In the Orang, as in the Chimpanzee and Gorilla, the salivary glands are large, especially the parotid gland, whose outline is triangular.
THE GIBBON.
The position, relations and appearances of the salivary glands are similar to those in the Chimpanzee, and the ducts have the same course and relations.
In the Orang and Siamang Gibbon the ducts of the submaxillary glands open on small papillae at the sides of the frenum linguse as in Man. But in all other
